Effect of mucilage edible coating on fresh-cut nectarine cultivar ‘Big Bang’
2022
The mucilage (OFI) obtained from cladodes of cactus pear (Opuntia ficus-indica) is useful to produce natural edible coatings to improve the shelf life of fruits. Edible coatings could be used to extend the shelf life of fresh-cut for products. The aim of this study was to evaluate the effect of (OFI) on quality of ‘Big Bang' nectarine slices. After cutting, nectarine slices were dipped in three different solutions: 1) distilled water, mucilage, glycerol (MC); 2) distilled water, mucilage, glycerol, Tween 20 (TW); 3) distilled water as control (CTR) and were stored for 3, 5, 7 and 12 days at 5°C and 90% RH, in polyethylene terephthalate (PET) packages under passive modified atmosphere condit…
Development and application of a new Edible Coating on fruits and fresh-cut fruits.
2014
Il progetto di ricerca ha come scopo il miglioramento della gestione post-raccolta dei frutti (interi e di IV gamma), intervenendo sull’estensione della shelf-life; valutando l’utilizzo di composti provenienti da materiali di scarto delle filiere produttive agroalimentari o risorse alternative da utilizzare come nuovi rivestimenti commestibili (edible coating: EC). La novità riguarda lo sviluppo di un edible coating a partire da residui vegetali di Posidonia oceanica, pianta acquatica mediterranea ampiamente diffusa sulle coste siciliane, responsabile di accumulo di biomassa sulle spiagge. Per soddisfare, in maniera efficace, l’obiettivo iniziale si vorrebbe creare una interazione tra 1-MCP…
Effect of drying condition on Leonforte peaches
2013
Leonforte peaches ripen in September and October and even as late as November. They are wrapped in paper bags to protect them from the wind and parasites and are harvested only when perfectly ripe. Protected inside the bags, they ripen late and take on a bright yellow colour with red streaks. Wonderfully scented, the peach boasts yellow, firm flesh that is sweet with a distinctive, slightly caramelized flavour. Aim of this paper was to set a drying process for fresh fruit transformation. In fact, the fruit harvest is limited in a very short time, so is important to find a conservation method. Drying process was carried out in a pilot plant setting different temperature and time condition. T…
Long-term monitoring of soil bulk density and erosion rates in two Prunus Persica (L) plantations under flood irrigation and glyphosate herbicide tre…
2021
Abstract Early season fruit production for the northern European market is highly intensive in fertilization, machinery, irrigation and the use of herbicides. Those conditions increase the soil losses and soil compaction and threaten the Sustainable Goals for Development of the United Nations by 2030. Long-term soil erosion measurements are necessary to determine the sustainability of agriculture managements. Moreover, soil erosion on flood irrigation land is a topic that request more surveys and research as rainfed sloping terrains attracted all the attention of scientists and research investment. Improved Stock Unearthing Method (ISUM) was applied to two 15 years-old herbicide treated fie…
Canopy Architecture Appraisal by Fractal Dimension of 'Flordastar' Peach Trees Grafted onto Different Rootstocks
2007
The objective of this research was to evaluate the modification of canopy architecture of ''Flordastar'' peach (Prunus persica L. Batsch) grafted onto rootstocks with different vigour, by the use of fractal dimension (D). The hypothesis was that different vigour rootstocks are able to modify the complexity of the branching pattern and that this effect can be assessed by a geometric parameter such as the fractal dimension (D) of the 2D projection of tree branching structure. The observations were carried out in a four-year-old experimental orchard of cv. ''Flordastar'' peach trees grafted onto Ishtara, Barrier, GF677 and MrS 2/5 rootstocks. On digital pictures of leafless, dormant peach tree…
Variability of sensory profile and quality characteristics for ‘Pesca di Bivona’ and ‘Pesca di Leonforte’ peach (Prunus persica Batsch) fresh-cut sli…
2015
Abstract Peach genotypes in Southern Italy include the white-flesh ‘Pesca di Bivona’ (‘Murtiddara’, ‘Bianca’, ‘Agostina’ and ‘Settembrina’) and the yellow-flesh ‘Pesca di Leonforte’ (‘Settembrina’, ‘Giallone’ and ‘Ottobrina’ ) landraces, with non-melting clingstone fruit, characterized by a persistent aroma and an excellent flavor that is highly appreciated by consumers. The aim of this work was to assess the suitability of these white- and yellow-flesh landraces to be processed as fresh-cut product with regard to the persistence of their quality and sensory profiles. Fruit of ‘Pesca di Bivona’ and ‘Pesca di Leonforte’ landraces were cut into slices and stored at 5 °C for 3, 5, 7, 12 d. Fre…
Effect of Drying Condition on the Quality of Dry Late Peaches of Leonforte
2015
The Late Peach of Leonforte [Prunus persica (L.) Batsch] grown in Southern Italy matures in September and October and as late as November. Fruits are wrapped in paper bags to protect them from parasites and are harvested only when fully ripe. Protected inside the bags, they ripen late and take on a bright yellow colour with red streaks. Highly aromatic, the peach has yellow, firm flesh that is high in soluble solids and has a distinctive, slightly caramelized flavour. The aim of this work was to deter¬mine the best method of drying peach as a means of conserving the fruit after harvest due to its very limited shelf-life. Drying processes were carried out in a pilot plant utilising differen…
Metabolomics approach to studying minimally processed peach (Prunus persica) fruit
2012
Fresh-cut fruit products for both retail and food service applications have increasingly appeared in the market place in recent years. Among different fruit types, peaches can be used and are highly appreciated as fresh-cut product although their commercial success is limited due to their short shelf-life and the quick onset of wounding-related physiological reactions. In this work we analyzed the technological and physiological changes induced by fresh-cut preparation in three different types of peach cultivars: 'Fayette' (melting), 'Wilhelmina' (non-melting) and 'Ghiaccio3' (stony hard). We performed a metabolite targeting profiling to focus on the changes in organic acid levels, importan…
